Cadonilimab with chemotherapy followed by concurrent chemoradiotherapy for locally advanced cervical cancer

Official title: A Phase III, Multicenter, Open-label, Randomized Controlled Clinical Study on the Treatment of Locally Advanced Cervical Cancer With Cadonilimab Combined With Chemotherapy Followed by Concurrent Chemoradiotherapy

Run by Union Hospital, Tongji Medical College, Huazhong University of Science and Technology · NCT07400536 · Data updated 2026-11-12

This phase 3 study will test whether adding cadonilimab to initial chemotherapy and then giving standard concurrent chemoradiotherapy helps women aged 18–70 with stage IIB–IVA locally advanced cervical cancer have better tumor responses and outcomes than standard chemoradiotherapy alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are women aged 18–70 with histologically confirmed squamous, adenocarcinoma, or adenosquamous cervical cancer at FIGO stage IIB–IVA, ECOG performance status 0–1, at least one measurable lesion, and adequate organ function who have not received prior antineoplastic therapy.

Probably not a fit

Patients with distant metastatic disease (FIGO stage IVB), prior total hysterectomy, inability to undergo brachytherapy, or those outside the age/ECOG/organ-function requirements are unlikely to benefit from enrollment.

What this trial studies

This randomized phase 3 trial compares an induction and concurrent immunotherapy strategy — cadonilimab combined with chemotherapy followed by standard external-beam radiotherapy plus brachytherapy and concurrent chemotherapy — against the current standard of concurrent chemoradiotherapy alone. Eligible patients are adults with histologically confirmed squamous, adenocarcinoma, or adenosquamous cervical cancer at FIGO stage IIB–IVA and at least one measurable lesion by RECIST v1.1. The study tracks efficacy endpoints (tumor response, progression-free and overall survival) and safety outcomes throughout treatment and follow-up. Treatments are delivered at a single lead center with standardized radiotherapy and chemotherapy protocols.

Why it matters

Potential benefit: If successful, the regimen could increase tumor response and prolong progression-free and overall survival for patients with locally advanced cervical cancer.

How similar studies have gone: Early-phase studies of cadonilimab and clinical experience with other PD-1/PD-L1 agents in cervical cancer have shown activity, but robust phase 3 evidence specifically for cadonilimab in this setting is still limited.

3. Patients with stage IIB-IVA cervical cancer (FIGO stage 2018) who had not received any previous antineoplastic therapy;
4. At least one measurable lesion according to RECIST v1.1;

6. Have adequate organ function.

Exclusion Criteria:

Subjects were excluded from the study if they met any of the following criteria:

1. Distant metastatic disease (including inguinal lymph node metastasis and lymph node metastasis above the level of the superior edge of the L1 pyramid in the proximal cephalic region, according to FIGO 2018 stage IVB);
2. He had undergone total hysterectomy (removal of the corpus uteri and cervix);
3. Inability to undergo brachytherapy or refusal to undergo brachytherapy for reasons such as anatomical abnormalities;
4. Had received any previous antineoplastic therapy, including but not limited to surgery (except biopsy), radiotherapy, or systemic therapy (chemotherapy, immunotherapy, targeted therapy);
